Omisha (Jacqueline Fernandez) -She is Armaan's fiancee and has an ethereal charm about her that is very magnetic and infectious. Omisha comes across as a person who can be banked on when the going gets tough. But behind this white, clean image, a grey shadow is lurking around. She is a nun who worships the devil.

Armaan Malik (John Abraham)-Armaan heads the Indian mafia in Turkey. While on one hand, he is famous for his easy way with women, on the other side lies a bottomless well of villainy. His tools of oppression are limitless. A network of hidden cameras and double dealings, a few traits of his multi-dimensional personality, are marshalled against those who stand in the way of his accumulation of money and power. Armaan may be extravagant, but he is never unrealistic. He runs his criminal empire with his half-sister Aleena.

Ranveer (Saif Ali Khan)- Ranveer, who is in his late 30s, is a mix of grit and sensitivity with a passion for horse racing. His business dealings border on the illegal and he is aggressive, always on the move. He walks with confidence and unsought arrogance. Ranveer can be extremely ruthless if betrayed – he never forgives or forgets. But behind this steely exterior is a caring heart. He believes in relationships and is fiercely protective about them.

Aleena (Deepika Padukone) -Beautiful, strong and passionate, Aleena is a ruthless mind dwelling in a beautiful body. The passion she inspires in the men she interacts with is instantly frozen into nothingness by her scalpel-slashing manner. She lives with Armaan in a palatial villa in Istanbul, the haven of high-stakes rollers.

R.D. (Anil Kapoor) -He is a flamboyant, retired police detective, who, in his late forties, is the owner of a lounge bar. A corrupt person, he has an unending greed for that extra buck. R.D. has a strange sense of humour and though he looks extremely harmless, he has another face hidden behind this facade. He is a genius when it comes to solving criminal cases.

Cherry (Ameesha Patel)Cherry, R.D.'s personal assistant, is dumb. Her unintentional, innocent flirting with R.D. and her pea-brained, whacky questions provide the much-needed humour to a grim crime scene. She is fiercely loyal to R.D. and keeps boosting his ego by complimenting him.
